Love this puzzle app. There's lots of puzzles & the interface is great. There is a banner ad at the bottom & optional ad for extra hints. No intrusive ads every minute or so like some games. The only problem is that not all 1's, & sometimes even larger groupings are placed on the board. These invisble groups make it impossible to solve the puzzles (especially the larger ones) without frequent hints. Because there's no clue to indicate these invisible groups are even there.

On the 4th page, on the 4th row the puzzles 2, 3 and 4 are provably unsolvable - there's a block of 5 squares with number 6 in it on the starting position.

Challenging but relaxing at the same time. There are no lives to lose and points to gain, it's just me and the numbers on the board and I know I'll win sooner or later. A small banner ad sits at the bottom of the screen all the time, discreet and easy to ignore. Fullscreen ads appear only when you switch to another app and return but can be closed immediately. Great game. Downsides: tutorial is not too helpful (but the basics are easy enough to figure out) and there are no sounds whatsoever.
